Hillary Clinton, Peter Pan, Pee-Wee Herman: What do these people have in common? They’re all now part of the beef between Wu-Tang Clan and Martin Shkreli.

Yesterday, rapper Ghostface Killah shared an 11-minute video with Reddit’s Hip-Hop Heads community—directed at the founder and former CEO of Turing Pharmaceuticals, who is widely reviled for hiking the cost of AIDS medications from $13.50 to $750, buying the sole copy of Wu-Tang’s album Once Upon a Time in Shaolin for $2 million, and being charged with securities fraud.

The beef began after Ghostface called Shkreli a “shithead” when asked by TMZ what he thought of the “pharma bro.” Shkreli, in turn, fired back with an insult of his own on Twitter:

When TMZ returned to Ghostface to ask for his reaction to the tweet (this is the age we live in), he saw Shkreli’s “Iron Man” comment and raised him a “Michael Jackson nose kid”:

Then Shkreli recorded a video—with three supporting “goons” in the background—mocking Ghostface for being “an old man that’s lost his relevance” and threatening to erase Ghostface’s contributions from Once Upon a Time in Shaolin if he “ever say[s] some dumb shit again.” Although it’s clear from the video that Shkreli’s opposition to saying dumb shit is pretty one-sided—as he calls Ghostface his “son,” comes dangerously close to quoting There Will Be Blood (“I butter your bread, understand me?”), and demands that Ghostface “write [him] a written apology.”

Which brings us to the latest update on the rapidly escalating feud: Ghostface’s new video.

It starts with a dressing-down of Shkreli’s physical appearance—as a “fake Peter Pan cat” and “fake-ass supervillain” with a “12-year-old body”—but quickly reminds viewers of his real crime: the price 5000% price hike of AIDS drug Daraprim.

“This is about AIDS right now,” Ghostface says in the video. “This is what you did to the people. To the American people and the people all over the world. I stand for them.”

Unfortunately, the promotional twist towards the end of Ghostface’s diss video may undermine his message. After bringing in his sister and mother to level their own insults at Shkreli, Ghostface inserts a plug for Wu Goo Cannabis Oil, a weed-derived panacea that “combats tumor & cancer cells,” “reduces seizures,” “combats anxiety & depression,” and “reduces blood sugar levels” (according to the video’s claims).

Shkreli has already issued a response on Twitter (three tweets and counting!), repeating his demand for an apology, tossing out another entry from his book of sick disses, and finally polling his followers to see who stayed “realest” (spoiler: Shkreli’s losing):

The format of your apology was unacceptable, @GhostfaceKillah. The consequences will never be the same. (Also, stop making medical claims.)

Despite the robust social media response, it seems unlikely that either party will let the feud end there. Since Ghostface responded to Shkreli’s 2-minute video with an 11-minute video, it stands to reason that Shkreli is obligated to respond with a video roughly 5 times longer—perhaps a feature-length “diss film” or a “diss mini-series.”

For now, redditors in the Hip-Hop Heads community are sitting back and enjoying the spectacle as another strange example of a distinctly 21st-century rap beef:
